This example shows a minimal SVG circle rendered on a blank HTML page, demonstrating the basic structure of a web-based visualization. The code uses plain HTML and CSS, with a single `<circle>` element inside an `<svg>` container, positioned at the default origin with a radius of 100 pixels. JavaScript is not utilized, so the circle remains static. The example serves as a starting point for understanding how to set up an SVG scene without any external libraries, highlighting the fundamental markup required for browser-rendered graphics.
